Nickel oxide -- Nanoparticles -- Band gap -- Magnetic properties
Аннотация: Nickel oxide nanoparticles were first synthesized by sputtering high-purity nickel in an oxygen plasma of a low-pressure arc discharge. The structure, morphology, and optical and magnetic properties of NiO nanoparticles were studied by XRD, TEM, FTIR, UV-VIS, and VSM. TEM images showed that the obtained NiO nanoparticles have a narrow particle size distribution and an average particle size of 12 nm. The XRD results and the processing of diffractograms by the Rietveld method showed that the obtained nanoparticles have a face-centered cubic lattice with an average particle size of 13 nm. With decreasing temperature, residual stresses increase and peaks corresponding to the superstructure appear. The band gap of NiO was determined from the optical absorption spectrum and amounted to 3.21 eV. Magnetic measurements showed that, at temperatures of 200 and 300 K, NiO nanoparticles, unlike bulk particles, exhibit ferromagnetic behavior, and at 5 K a magnetic hysteresis loop appears. Based on the studies, a dendritic model of the nanoparticle microstructure is proposed.

silicene -- germanene -- 2D ferromagnetism -- X-ray magnetic circular dichroism (XMCD) -- monolayer
Аннотация: Two-dimension (2D) magnets have recently developed into a class of stoichiometric materials with prospective applications in ultra-compact spintronics and quantum computing. Their functionality is particularly rich when different magnetic orders are competing in the same material. Metalloxenes REX2 (RE = Eu, Gd; X = Si, Ge), silicene or germanene — heavy counterparts of graphene — coupled with a layer of rare-earth metals, evolve from three-dimension (3D) antiferromagnets in multilayer structures to 2D ferromagnets in a few monolayers. This evolution, however, does not lead to fully saturated 2D ferromagnetism, pointing at a possibility of coexisting/competing magnetic states. Here, REX2 magnetism is explored with element-selective X-ray magnetic circular dichroism (XMCD). The measurements are carried out for GdSi2, EuSi2, GdGe2, and EuGe2 of different thicknesses down to 1 monolayer employing K absorption edges of Si and Ge as well as M and L edges of the rare-earths. They access the magnetic state in REX2 and determine the seat of magnetism, orbital, and spin contributions to the magnetic moment. High-field measurements probe remnants of the bulk antiferromagnetism in 2D REX2. The results provide a new platform for studies of complex magnetic structures in 2D materials.

ferromagnetism -- single-ion anisotropy -- orientational phase transition
Аннотация: The ground state of a Heisenberg ferromagnet with the noncollinear single-ion anisotropy axes of two magnetic sublattices has been investigated in an external magnetic field applied in the anisotropy axes plane. Noncollinearity of the sublattice local anisotropy axes leads to a new effect called the orientational first-order spin-flop phase transition. The transition field depends on the single-ion anisotropy value and sublattice local axes orientation. An analysis of the stability of magnetic states shows that the transition is accompanied by the hysteretic field dependence of the magnetization. The dependences of the spin-flop transition field, magnetization jump, and susceptibility on the single-ion anisotropy value and axes orientation have been determined. The results obtained are used to explain the field dependence of the magnetization in the PbMnBO4 ferromagnetic crystal.

Аннотация: A non-standing characteristic of directly imaged spin-waves in confined micrometer-sized ultrathin Permalloy (Ni80Fe20) structures is reported along with evidence of the possibility to alter the observed state by modifications to the sample geometry. Using micromagnetic simulations, the presence of the spin-wave modes excited in the Permalloy stripes along with the quasi-uniform modes was observed. The predicted spin-waves were imaged in direct space using time resolved scanning transmission X-ray microscopy, combined with a ferromagnetic resonance excitation scheme (STXM-FMR). STXM-FMR measurements revealed a non-standing characteristic of the spin-waves. Also, it was shown by micromagnetic simulations and confirmed using STXM-FMR results that the observed characteristic of the spin-waves can be influenced by the local magnetic fields in different sample geometries.

Аннотация: We analyze the influence of cooperative effects on the magnetic properties and spin crossover between the high-spin (HS) term S = 5/2 and low-spin (LS) term S = 1/2 in Mott–Hubbard dielectrics with 3d5 ions under high pressures. Two cooperation mechanisms (superexchange interaction and effective interaction via the elastic system) are considered. The sign of the exchange interaction changes because of the crossover from the antiferromagnetic in the HS state to the ferromagnetic in the LS state. In view of the large difference between the ionic radii of the HS and LS states, the systems with spin crossover acquire an additional strong coupling via the elastic system. Using the Hubbard operator representation and considering the electronic states of the two terms simultaneously, we obtain the effective Hamiltonian with allowance for the cooperative effects. The magnetic phase diagram and the spin crossover are investigated in the mean field approximation. It is shown that the inclusion of cooperative effects at low temperatures leads to a first-order phase transition between the antiferromagnetic HS state and the ferromagnetic LS state. At higher temperatures, more complicated sequences of phase transitions are possible upon an increase in pressure, including the HS paramagnet–HS antiferromagnet–LS paramagnet and HS antiferromagnet–LS paramagnet–LS ferromagnet transitions.

Аннотация: The simple lattice and magnetic structure, the high Neel temperature, the narrow antiferromagnetic resonance line of FeBO3, and the narrow electron paramagnetic resonance line of its isostructural diamagnetic analogs MBO3:Fe3+(M = Ga, In, Sc, Lu) make iron borate unique for investigations and applications. Iron borate is a model crystal for numerous experimental and theoretical studies, including spin crossovers and metallization at megabar pressures and many-electron effects in optics and X-ray spectroscopy. The recent works dealing with the investigation of the properties of FeBO(3)are reviewed.

Аннотация: The inertial dynamics of magnetization in a ferromagnet is investigated theoretically. The analytically derived dynamic response upon microwave excitation shows two peaks: ferromagnetic and nutation resonances. The exact analytical expressions of frequency and linewidth of the magnetic nutation resonance are deduced from the frequency-dependent susceptibility determined by the inertial Landau-Lifshitz-Gilbert equation. The study shows that the dependence of nutation linewidth on the Gilbert precession damping has a minimum, which becomes more expressive with increase of the applied magnetic field.

Аннотация: Magnets derived from inorganic materials (e.g., oxides, rare-earth–based, and intermetallic compounds) are key components of modern technological applications. Despite considerable success in a broad range of applications, these inorganic magnets suffer several drawbacks, including energetically expensive fabrication, limited availability of certain constituent elements, high density, and poor scope for chemical tunability. A promising design strategy for next-generation magnets relies on the versatile coordination chemistry of abundant metal ions and inexpensive organic ligands. Following this approach, we report the general, simple, and efficient synthesis of lightweight, molecule-based magnets by postsynthetic reduction of preassembled coordination networks that incorporate chromium metal ions and pyrazine building blocks. The resulting metal-organic ferrimagnets feature critical temperatures up to 242°C and a 7500-oersted room-temperature coercivity.

(Co + Al)-doped ZnO -- Co-doped ZnO -- Diluted oxides -- Thin films -- Hydrogenation -- Room temperature ferromagnetism
Аннотация: (Co + Al)-doped ZnO films have been synthesized by the RF magnetron sputtering. Films of this composition have first been obtained in mixed atmosphere of Ar + H2. High hydrogen concentration of 20–50% has been used together with high enough substrate temperature of 450 °C. The used technological conditions affected the morphology, chemical composition, optical, electric, and magnetic properties of the films to an even more than in the case of Co-doped ZnO films synthesized under the same conditions and studied earlier. The films exhibit ferromagnetic behavior at room temperature with much greater magnetization and magneto-optical activity compared to the Co-doped films. At the same time, the hydrogenated films show an increase in electric conductivity in comparison with samples synthesized in the atmosphere of Ar + O2. The magnetic nature of the hydrogenated films has been associated with the defect-related mechanism.

Аннотация: Amorphous ferromagnetic materials with variable composition are promising candidates for application in rapidly-growing technological fields, such as spintronics. However, the significant downside of current state-of-the-art materials is a conductivity mismatch between the injector and the semiconductor, which often is associated with the inability to control and precisely tailor the magnetic properties and conductivity. We report on the synthesis of soft-magnetic SiCxNy:Fe films with a saturation magnetization of 20 emu cm−3 and a conductivity similar to the one of Si, which is crucial for possible applications. XRD with synchrotron radiation and EXAFS revealed the complex composite structure of the films: crystals of Fe3Si, Fe5Si3, SiC and graphite are embedded into the amorphous matrix of SiCxNy. Variation of the deposition conditions allowed us to separately control the magnetic properties through the iron concentration and the conductivity of the material through the amorphous SiCxNy matrix composition. The reported results revealed significant potential of SiCxNy:Fe films as a prospective object for analysis of spin-polarized transport in amorphous semiconductors and for application in the field of spintronics.

Аннотация: Orthorhombic Pb2Fe2Ge2O9 antiferromagnetic single crystals have been synthesized by a modified pseudo-flux technique and their magnetic, thermodynamic, and magnetodielectric properties have been investigated. It has been found that, below the Ned temperature (45.2 K), iron moments are arranged in a canted antiferromagnetic structure with a weak ferromagnetic moment parallel to the a axis. According to the specific heat measurement data, the T-N value remains invariable in applied magnetic fields of up to 50 kOe within the experimental accuracy. The magnetic entropy in the investigated crystals attains 2Rln(2S + 1) right above T-N, which is indicative of a purely magnetic nature of the transition. It has been shown that the weak ferromagnetic moment is induced by the interplay between the single-ion anisotropy and antisymmetric Dzyaloshinskii-Moriya exchange interaction, with the latter contribution being dominant. It has been established from the angular dependences of the magnetization in three orthorhombic planes that the symmetries of the magnetic and crystal structure are identical. The magnetodielectric properties of the Pb2Fe2Ge2O9 single crystals have been studied at different mutual orientations of the electric and magnetic fields. The most prominent anomalies have been observed in the vicinity of the spin-flop transition in a magnetic field applied along the c axis.

Аннотация: A system of equations describing the ground state in an external magnetic field has been obtained for a twoposition antiferromagnet with noncollinear axes of single-ion anisotropy of moments of different sublattices. It has been shown that the antiferromagnetism vector changes sign at a spin-flop transition. This leads to a first-order magnetic phase transition with hysteresis in the field dependence of the magnetization. Explicit relations have been obtained between the parameters of a microscopic Hamiltonian and the experimentally observed spontaneous moment and spin-flop transition field. It has been shown that the field dependence of the total magnetic moment of the antiferromagnet with magnetic ions at two crystallographically nonequivalent positions (two-position antiferromagnet) obtained within the two-sublattice model is nonlinear above the transition field at any orientation of the crystal with respect to the magnetic field.

Аннотация: The collective magnetization motion in an array of magnetostatically interacting ferromagnetic square elements is studied theoretically and experimentally. Dispersion laws are obtained for collective modes for some particular cases of the distribution of the topological charges π T of magnetic vortices in particles. Resonance curves are plotted with allowance for dissipation for various values of π T . An experimental investigation of the ferromagnetic resonance in a two-dimensional array of particles qualitatively supports the calculation results.

Аннотация: The PbMn1−xFexBO4 (x ≈ 0.1) orthoborate single crystals have been grown for the first time by spontaneous crystallization and their magnetic and resonance properties and specific heat have been examined. It has been established that partial substitution of iron ions for manganese ones leads to an increase in the Curie temperature to 34.2 K from its value of 30.3 K in the unsubstituted crystal, enhances the magnetic anisotropy, and reduces the saturation magnetization. The magnetization drop is explained in the framework of the model of a ferrimagnetic-like structure, in which the magnetic moments of iron and manganese ions form ferromagnetic subsystems coupled by the antiferromagnetic exchange. It has been found that under magnetization along the rhombic b axis the magnetic moments switch stepwise to the magnetic field direction in a certain critical field. The spin-reorientation transition is the first-order one. This feature of the crystal magnetization does not allow the experimental ferromagnetic resonance frequency-field dependence for the rhombic b axis to be described using the calculation for a simple rhombic ferromagnet. It has been established that the increase in the magnetic anisotropy of the crystal upon substitution leads to an increase in the energy gap in the ferromagnetic resonance spectrum to 121.5 GHz at T = 4.2 K.
